Abstract
This paper deals with the mechanical properties of surface modified cellulose fiber-filled thermoplastic composites. The surface modifications were carried out by using maleic anhydride (MA) as a coupling agent. MA-coated fibers provided a positive response with regard to the mechanical properties of composites. On the whole, these properties improved compared to those of virgin polymers. The influence of two organic peroxides, e.g., benzoyl peroxide (BPO) and dicumyl peroxide (DCP), on the properties of composites was also studied. The concentration of MA, initiators and wood fibers plays an important role on the mechanical properties of the composites, e.g., properties improved along with the rise in concentration of each of the above, up to a certain limit, and then decreased at higher concentrations. Moreover, properties varied with the change in type of cellulose fiber, e.g., CTMP aspen, sawdust aspen and nutshell, and nature of thermolastic, e.g., polyethylene and polystyrene. As far as the mechanical properties of the composites were concerned, DCP was believed to be a better initiator.
